A system for obstructing unauthorised access to a socket 101 comprises a socket blocker removal tool 126 and a socket blocker 100. A pin extending from the socket blocker body 102 is configured for insertion into, and retention within, an aperture defined by a body of the socket 101. The socket blocker 100 has a first formation that, upon engagement with a co-operating second formation of the removal tool 126, enables an authorised user to extract the socket blocker pin from the socket aperture and gain access to the socket 101. The first formation may have a removal surface located within the socket blocker body 102 and may have a receiving aperture 103 with first and second aperture portions of first and second cross-sectional shapes. A key portion 128 with a cross-sectional shape complementary to that of the first cross-sectional shape may protrude from a shaft of the removal tool 126. When the removal tool 126 is engaged with a cam surface of the removal surface and rotated relative to the socket blocker 100, the tool 126 may also engage with the socket 101 to urge the pin at least partially out of the socket aperture. |
